An attempt is made to guess the overall cosmic abundance of
`metals' and the contribution made by the energy released in their
production to the total intensity of extragalactic background
light (EBL). With a comparable or somewhat larger amount coming
from white dwarfs, and a probably quite modest contribution from
AGNs, one can fairly easily account for the lower end of the range
of existing estimates for the total EBL intensity (50to 60 nwt
m$^{-2}$ sterad$^{-1}$), but it seems more difficult should some
higher estimates (90 to 100 in the same units) prove to be
correct.
